<H3>Description.</h3>
|
||
|
|
<P>
|
||
|
|
<strong>mbpasswd</strong> is the wrapper for the <strong>passwd</strong> program
|
||
|
|
is present on all Linux systems. To use <b>passwd</b> to change the password of
|
||
|
|
another user is only allowed by <b>root</b>. The mbpasswd program overcomes this limitation.
|
||
|
|
The wrapper <b>mbpasswd</b> is run from the bbs by user <b>mbse</b> when an ordinary
|
||
|
|
user is logged in the bbs. The program is called when a new user logs in the bbs or
|
||
|
|
when an excisting user changes his password. His password under Unix is then always the same as his
|
||
|
|
password in the bbs program. This is necessary for the user to be able to get
|
||
|
|
his email using the pop3 protocol.<P>
|
||
|
|
You never need to run <strong>mbpasswd</strong> by hand, in fact it is protected so that only
|
||
|
|
members of group <b>bbs</b> are allowed to use it.
|

<H3>Environment.</H3>
|
||
|
|
<P>
|
||
|
|
<strong>mbpasswd</strong> must be installed setuid root and setgid root, ls -la looks like this:<br>
|
||
|
|
<pre>
|
||
|
|
-rws--s--x 1 root root 6644 Jun 26 21:23 /opt/mbse/bin/mbpasswd*
|
||
|
|
</pre>
|

<H3>Commands.</H3>
|
||
|
|
<P>
|
||
|
|
<code><strong>mbpasswd</strong> [-opt] [username] [password]</code> for example:<br>
|
||
|
|
<pre>
|
||
|
|
mbpasswd -f michiel secret
|
||
|
|
</pre>
|
||
|
|
Valid options are <strong>-f</strong> (forced), this will also change locked passwords,
|
||
|
|
this has only effect if your system uses shadow passwords. If you use
|
||
|
|
<strong>-n</strong> as option, locked passwords cannot be changed. For a new user the
|
||
|
|
<b>-f</b> option is used by <b>mbsebbs</b>, when a user changes his own password the
|
||
|
|
<b>-n</b> option is used.
